Effects of long-term exposure to ammonium sulfate particles on growth and gas exchange rates of Fagus crenata, Castanopsis sieboldii, Larix kaempferi and Cryptomeria japonica seedlings
•Four Japanese forest tree species were exposed to submicrometer (NH4)2SO4 particles.
•No significant effect of the particles on growth was observed after 2 years exposure.
•Net photosynthetic rates of 3 species were not significantly changed by the exposure.
•Net photosynthesis of Cryptomeria japonica was relatively sensitive to (NH4)2SO4.
•Both increase and reduction in net photosynthetic rate were observed in C. japonica.
